Problem 2.9: The animation simulates the motion of a helium balloon

Please wait for the animation to completely load.

The animation simulates the motion of a helium balloon with the effect of air resistance neglected. A graph of y velocity vs. time for the balloon is also shown (position is given in meters and time is given in seconds). Restart.

Is the y velocity increasing, decreasing, or constant?

Is the y acceleration increasing, decreasing, or constant?

What is the acceleration of the balloon?
